LIGNIN-KMC: A Toolkit for Simulating Lignin Biosynthesis [PDF]

ACS Sustainable Chemistry & Engineering, 2019
Lignin is an abundant biopolymer of phenylpropanoid monomers that is critical for plant structure and function. Based on the abundance of lignin in the biosphere and interest in lignin valorization, a more comprehensive understanding of lignin biosynthesis is imperative. Here we present an open-source software toolkit, LIGNIN-KMC, that combines kinetic
